If you're intimating that someone from Tesla put the definition into Wikipedia
No, I'm intimating that the Wikipedia definition is not the one used if you were to ask the general public.
No. It's the definition you would probably find in the manual for an airplane. It's called reality. Go ask a pilot if they sleep while autopilot is on. They could lose their license. And if that isn't enough, when you activate autopilot on a Tesla, you are warned that it requires an alert human driver. And if even that isn't enough, perhaps you might get the hint when the car keeps reminding you to keep your hand on the wheel if you haven't touched it in two minutes.
